Some say Jenkins might be able to handle LT, maybe after a year at RT. The thing is RTs face explosive pass rushers too (like Kahlil Mack), but the QB usually has better view of the right side of the line.
Lots of potential options. Some mocks have Darrisaw dropping. If he doesn't do the Bears trade down and take a Mayfield, Cosmi or Radunz.
As for Monds, and possibly Mills I think some of the QB hungry teams that missed out on QB in R1 will be snagging one of these guys in R2. I'd hate to have to use a R1 pick on one of these QB - maybe trade up the pick at 52 instead.
